DECORATIVE TREATMENT oF WOODEN SURFAC'ES.

SPECIFICATION forming part of Letters Patent No. 649,978, dated May 22, 1900.

Application filed J'anuary 17,1899. Serial No- 70Z,468, (No specimens.)

To all whom it may concern:

Be it known that I, HERMANN BUYTEN, a citizen of the German Empire, and a resident of Dusseldorf, Germany, have invented certain new and useful Improvements in the Decorative Treatment of Wooden Surfaces,

' of which the following is a specification.

removed. Fig. 4 is a cross-section on line 4 4,

Fig. 3. Fig. 5 is a face view of the wooden body, showing it finished and after the coating has been removed; and Fig. 6, a cross-see tion on line 6 6, Fig. 5.

The wooden body A is in the well=known manner first rendered even and smooth by planing, grinding, polishing,- or similar operations, or it is provided with relief ornaments by engraving or cutting, or it is inlaid with wood, metal, or other suitable material. Subsequently those parts a which are not to be touched by the sand-blast, but intended to form a smooth pattern in the grained woodfor instance, the inlaid or engraved parts-are protected against the sand-blast by a protective coating 1), which is attached to the surface of the 'wood. This protective coating may consist of prepared paper, india-rubber, or other suitable material adapted to resist the sand-blast.

For securing the protectivecoating to the wooden surface I use an adhesive substance mixed with glycerin or other material adapted to facilitate the subsequent removal of the I coating.

Instead of applying a protective coating by means of an adhesive substance those parts of the surface on which the sand-blast is not intended to operate are coated with a suitable protective substance made so that it can be easily removed after the operation.

If after the sand-blast treatment the protective coating 1) is removed, those parts a which have been thus covered will be found to project slightly over the remainder of the surface and to be smooth, while on the eX-- blast process and also any splinters of wood which may still adhere to the surface. The parts which have not been touched by the sand-blast may remain smooth or they may be further treated in any desired manner.

If the wood is to be stained, the ornaments may easily be colored differently from the parts treated with the sand-blast. In this case the stain is applied to the wood before the protective coating has been removed, so that only the parts treated with the sandblast will be stained, while the ornamental parts remain free from the staining liquid, or the surface may be stained again after the removal of the protective coating, preferably with a lighter-colored stain, so that the ornaments will have a lighter color than the remainder of the surface, or this treatment may be further modified by removing only a portion of the protective coating be fore the secondstaining and applying an additional stain after the complete removal of the coating. In this manner any desired number of shades or colors may be produced on the wood. The wood may, however, be stained before the application of the sandblast, and after the latter has been applied,- but before the protective coating has been removed, the low-lying part may be treated with a stain of a different color.
